' IMPROVEMENT IN CAR-P USHERS.

Specification forming part of Letters Patent No. 211,324, dated January14, 1879; application filed October 28, 1878. I

To all whom it may concern:

Be it known that I, J. W. FESSENDEN, of Lockport, in the county ofNiagara and State of 1i ew York, have invented certain new and usefulImprovements in Gar-Pushers; and I do hereby declare that the followingis a full, clear, and exact description of the invention,

which will enable others skilled in the art to which it appertains tomake and use the same,

My invention relates to that class of car- .pushers in which a pivotedlever-bar is employed for starting the Wheel of a car. My

improvement has special reference to the carpusher shown in Patent No.161,439.

Referring to the drawing, A represents the lever, which is composed ofthe metallic portion f, the wooden handle f, and the semicircularprojection a upon the under side of the metallic portion f. Thissemicircular projection has a pintle-socket, a, for the reception of thepintle H, which is employed simply for the purpose of keeping the leverin place, but not as an absolute bearing for the same.

The base B has two projecting jaws, b, betwecn which the lever ispivoted by the pintle H. This pintle does not, however, constitut-e. thebearing for the lever, as the'said base has a concave recess, 0, formedin its body, and corresponding in shape to the semicircular projection aupon the metallic portion f of the lever. The lever is so pivoted thatits semicircular projection a rests upon the interior surface of thesocket, thereby removing the strain from the fulcrum to the base. 7

The metallic portion f has a socket for the reception of the woodenhandle f which is secured therein by a screw or bolt, 8, and it is alsoprovided w gives it additional strength.

ith a bead or ring, 1", which The part f has a tapering form, as shown,and is beveled at d, so that it will conform to the shape of the wheel,in order to obtain a better purchase upon the same.

The semicircular projection a is east solid with the part f, andconforms in shape to the concavity c in the base B.

The pintle H is passed through the jaws b and secured by a nut, p.

y The vertical clutch E is secured to the base by bolts *5 z. Nuts 1 arefitted upon the ends of these bolts. The clutch-plate E is arched, asshown, so that it will fit upon the rail.

The base B is arched as shown in Fig. I, in order to save material andgive it requisite lightness.

By my construction the semicircular projection a is not reduced inwidth, as heretofore, but is equal in width to the widest portion of themetallic part f of the lever. The strain is removed from the pintle tothe base, since the semicircular projection rests in the socket c, andby thus forming a bearing in the solid body of the base, which is equalin width to the widest portion of the lever, a stronger-and more durabledevice is obtained than if the semicircular projection a were reduced inwidth and pivoted between" jaws, as heretofore.

What I claim is- In a railroad-car pusher, the herein-described base B,adapted to be fitted upon a rail, substantially as set forth, and formedwith a concavity, 0, below and between the jaws b, and equal in width tothe distance between the same, in combination with the lever having asemicircular projection, a, equal in width to the part f, and having itsbearing in the concavity c, substantially as shown and specified.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
